Input Parameters

18.2 RLS-EXT-CONT

(Cisco ONS 15454 SDH) The Release External Control (RLS-EXT-CONT) command releases a forced contact state and returns the control of the contact to an AUTOMATIC control state.

Usage Guidelines

In AUTOMATIC control state, the contact can be opened or closed depending on triggers that might or might not be provisioned in the NE. Therefore, issuing a RLS might not produce any contact state change.

The NE defaults to having no triggers provisioned for external controls, which consequently produces default open contacts. An NE with this default provisioning will always produce an open contact with a RLS-EXT-CONT command.

The duration is not supported; it defaults to CONTS.

In an automatic state, the contact could be opened or closed depending on the provisioned trigger. Therefore, issuing an OPR-EXT-CONT command followed by an RLS-EXT-CONT command might not produce any contact state change.

The RLS-EXT-CONT is not allowed during the MNTRY duration. The command is allowed for the CONTS duration. The length of MNTRY duration is set to be 2 seconds.

RLS-EXT-CONT cannot change the contact state to Automatic if the existing state is Manual Open.

Input Format

RLS-EXT-CONT:[<TID>]:<AID>:<CTAG>[::,];

Input Example

RLS-EXT-CONT:CISCO:ENV-OUT-2:123;

Input Parameters

<AID>

Access identifier from the “ENV” section. Identifies the external control being released.

Usage Guidelines

The value CRS for the LPBKTYPE parameter is applicable only for the VC modifier. The FACILITY and TERMINAL values for LPBKTYPE parameter are applicable to the ports.

The optional [<LPBKTYPE>] field defaults to the current existing loopback type.

FEAC loopbacks can be released by specifying LINE as the loopback type and FEND as the location.

FEAC loopbacks on the DS1 interface of a DS3XM card can be applied only if a Virtual Tributary (VT) connection has been created on it. An attempt to operate or release FEAC loopbacks in the absence of a VT connection will result in an error message.

18.7 RLS-PROTNSW-<STM_TYPE>

Usage Guidelines

The release of a protection switch request is applicable only to the OPR-PROTNSW protection switch commands, the user-initiated switch protection commands.

Use the RTRV-COND-ALL or RTRV-ALM-ALL command to retrieve the protection switching state (manual, lockout, forced).

DIRN is an optional parameter. A NULL value defaults to BTH for a MS-SPRing protection, BTH for 1+1 bidirectional protection group, and RCV for 1+1 unidirectional protection group.

DIRN follows these rules: TRMT will always fail for any kind of protection groups. For two-fiber and four-fiber MS-SPRing protection groups, both the RCV and TRMT directions will fail.

DIRN is applicable for both 1+1 and MS-SPRing protection groups. OPR-PROTNSW applies to a MS-SPRing span/ring as shown by the following command:

RLS-PROTNSW-STM16::FAC-5-1:A::BTH;

This command instructs the NE to release a line protection switch request between a working line and a protection line.

The following actions will return error messages:

This command is not used for the common control (TCC2, TCC2P, TCC3, XC-VXL-10G, XC-VXL-2.5G, or XC-VXC-10G) cards. Sending a command on a common control card will return an Input, Invalid Access Identifier (IIAC) error message. To switch common control cards, use the SW-DX-EQPT and ALW-SWDX-EQPT commands.

Sending this command to non-SDH (STM) cards will return an Input, Invalid Access Identifier (IIAC) error message. To switch a non-SDH card, use the ALW-SWTOPROTN-EQPT, ALS-SWTOWKG-EQPT, INH-SWTOPROTN-EQPT, and INH-SWTOWKG-EQPT commands.

Sending this command to query on a card that is not in a protection group will return the Status, Not in Valid State (SNVS) error message.

Sending this command to a working card that is failed or missing will return the Status, Working Unit Failed (SWFA) error message.

Sending this command to a protect card that is failed or missing will return the Status, Protection Unit Failed (SPFA) error message.

Sending this command to a card that is not in protection will return the Status, Not in Protection State (SNPR) error message.

Sending this command to an STM line that is already in clear mode will return an Already in Clear Maintenance State (SAMS) error message.
